I forget how to set the heapsize in Hl2, and I asume it's the same command for Emergence. I noticed that the heap size is only 64 mb. I have 2 gigs of ram and could easily put the heap to 512 or 1 gig. I know you put it in the the launch options, but I forget the command. I'm going to look for it, but if you know just respond and let me know.
